CURTAIN-POLE..

SPECIFICATION forming part of Letters Patent No. 780,166, dated January 17, 1905.

Application filed June l, 1904. Serial No. 210,717.

To all 'wl/1,0m t may concern:

Be it known that I', OI-[ARLEs G. Fos'rnn, a citizen of the United States, residing at North English, in the county of 4Iowa and State of Iowa, have invented a new and useful Ourtain- Pole, of which the 'following' is a specification.

This invention relates to curtain-poles of that class which embodies an outer tubular member and an anchor member to clamp a curtain between the members, and has for its object to facilitate the assembling of the mem- -bers to grip the curtain between the members by the weight of the curtain, and thereby to obviate extraneous clamping means operating' upon the anchor member to prevent tilting' and loosening of the anchor member under the strain of the weight of the curtain and to prevent slipping of the curtain 'from between the pole and the anchor members.

l/Vith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying' drawings, and particularly pointed out in the appended claims, it being' understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without depart` ing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure l is a perspective view of a curtain-pole embodying' the features of the present invention. Fig. 2 is a longitudinal sectional view thereof. Fig. 3 is a cross-sectional view thereof. Fig. t is a similar view illustrating a step in the manner of assembling the pole members. Fig. 5 is a cross-sectional view of a modified form of pole. Fig. 6 is a similar view of another form of pole.

Like characters of reference designate corresponding parts in each and every ligure of the drawings.

Referring at first more particularly to Figs. 1 to 3, inclusive, of the drawings, it will be seen that the present pole is made up of a pair of telescoped tubular members 1 and 2, respectively, each of which is closed at its outer end, as best indicated, in Fig. 2 of the drawings. The tubular pole members may vary considerably in shape, as indicated in the several figures of the drawings, the shape shown in Figs. l to 3, inclusive, being' substantially cylindrical, with its lower side flattened, as indicated at 3. A longitudinal slot i is 'formed in the fiattened under 'face of each tubular member, with its outer end closed by the outer closed end of the pole member and its inner end intersecting the inner end of the pole member in order that the inner end poi'- tions of the slots of the two members may register throughout the overlapped portions of the members. [t is preferred to have the slot 4 located at one side of the longitudinal center of the iiat under face o'f the tubular pole member fora purpose that will be hereinafter described. The anchor member 5 is in the form of a flat rod or bar of a thickness to permit of the same being passed through the slot L and of a width to project at opposite sides of the slot and close the same when iitted within the tubular pole.

In assembling' the pole and anchor members the upper portion of a curtain 6 is passed over the anchor-bar member 5, and then the bar, with the curtain embracing the same, is inserted in an edg'ewise direction through the slot and into the interior of the tubular member and then adjusted to overlap the opposite edges of the slot, with the opposite portions of the curtain embracing the edges of the bar and passing' downwardly throi'lgh the slot. It will now be understood that the slot is formed at one side of the longitudinal center of the under flattened 'face of the tubular meinber in order that the bar may be conveniently forced into the tubular member without engaging' the opposite side thereof before the bar has been entirely inserted into the member. After the bar has been placed within the tubular member the opposite portions of the curtain are of course drawn downwardly, so as to snugly embrace the bar, and then the longer portion of the curtain (indicated at 6 in Figs. 3 to 6, inclusive) is drawn downwardly, so as to shift or slide the anchor-bar across the slot until stopped by engagement with one of the uprig'ht walls of the tubular pole member, after which the weight ,of the curtain is suflicientto hold the anchor-bar IOC against said wall of the tubular pole with the curtain wedg'ed between the pole and the anchor device sufiiciently to prevent slipping of the curtain from between the pole and the anchor device. Furthermore, the curtain is also wedged between the anchor device and the edges of the slot through which the curtain depends.

It will here be noted that the looseness or play of the anchor member transversely across the slot 4 is a very important feature of this device in that it permits of the anchor device being moved to wedge the curtain between one edge of the anchor-bar and the tubular pole and also permits of the anchor-bar being moved out of engagement with said upright side of the pole and then tilted so as to be withdrawn through the slot when it is desired to remove the anchor-bar and the curtain from the pole.

Then the pole member is triangular in shape, as shown in Fig. the upstanding wall of the pole against which the anchor-bar grips the curtain overhangs the bar sufficiently to form a stop to prevent tilting of the bar under the weight of the long portion 6 of the curtain, wherefore the anchor-bar cannot be accidentally tilted and displaced through the slot 4.

Should the shape of the tubular member be such as not to effectually prevent tilting' of the anchor-bar under the action of the weight of the curtain-as, for instance, in the tubular form shown in Figs. l to 4, inclusive-one or more pins7 are passed through the pole at an inclination to the vertical transversely across the top of the anchor-bar, with the lower end portion of each pin disposed in position to engage the upper portion of the bar at that edge thereof which is held in contact with the adjacent side of the pole under the action of the weight of the curtain, thereby to form the desired stop to prevent accidental tilting of the anchor-bar. If desired, that edge portion of the anchor-bar which is drawn into engagement with the pins 7 may be beveled, as at 5, to secure a broad bearing against the pin and produce a wedging action upon the curtain between the beveled edge of the anchor-bar, the pins, and the upstanding side of the curtain-pole.

In Fig. 6 there has been shown another modied form of tubular pole member 8, which is substantially oblong` in cross-section with the wider flange 9 at one side of the slot l0 inclined downwardly and inwardly to accommodate the flat bar 11 in inserting and removingthe same, and one of the upper edges of the bar is beveled, as at l2, to also facilitate the entrance of the bar through the slot. These changes are necessary in view of the comparative shallowness of the tubular member, which necesitates the insertion of the bar member at a sharper inclination than is necessary in a tubular member of cylindrical or triangular shape.

From the foregoing description it will be apparent that the present device embodies a tubular pole and an anchor member only, and these parts are so constructed as to eifectually grip a curtain between the same under the strain of the weight of the curtain without any extraneous clamping means whatsoever. Moreover, these parts are so constructed and arranged as to permit of their convenient assemblage and attachment for hanging and taking down curtains, and the latter are not damaged as when the ordinary curtain-pins are employed, for the reason that each curtain is gripped throughout its entire width between the pole and the anchor member, and therefore is neither punctured nor torn in the operation of putting up and taking down the curtain.

Having thus described the construction and operation of my invention,what I claim as new` and desire to secure by Letters Patent, is-
